Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a light such as a desk lamp whose irradiation position can be freely adjusted.

The present invention is characterized in that it consists of a reflecting mirror provided with a plurality of different reflecting surfaces and a light source, and by selecting any of the different reflecting surfaces, the spreading surface from the light source can be arbitrarily varied. It is a reflective light.

Embodiments of the present invention will be explained with reference to FIGS. 1 to 6.
Figure 1 shows a light in which a pedestal 2 is rotatably supported on a base 1, and a light source 3 and an arm 5 with a mirror 4 supported on the pedestal 2 are provided on the pedestal 2. The entire structure can be tilted and fixed in any direction by movement. The light source section 3 houses a light source lamp 6 and a Fresnel lens 7 that condenses the light.The inner surface of the light source section is used as a reflection condenser mirror 8 for the lamp 6, and the heat of the lamp is transferred to hot air 10 through a gap 9 on the outer periphery of the Fresnel lens 7.
Dissipates as The mirror 4 is a double-sided mirror with one side convex and the other side concave, and is pivoted on the arm 5, and is rotated to reflect the light A from the light source on the convex mirror as irradiation light B or on the concave mirror. to switch to spot irradiation. Arm 5
The beam expands and contracts by sequentially passing through pipes of different diameters, and the inclination of the pedestal 2 allows the arm 5 to expand and contract, and the mirror 4 to rotate, making it possible to greatly change the irradiation location. 17
is a lamp switch.

FIG. 2 shows a pestle 12 supporting the double-sided mirror 4 shown in FIG. A punch 15 is supported on the base 11 parallel to this, and a light source part 1 is attached to this and the punch 13.
6 is attached so that it can be freely locked in the upper and lower positions.

18 is a condensing lens, 19 is a heat vent hole, and 20 is a light source part 16
The receiving stopper 21 is a condensing mirror that reflects the light from the light source lamp 6.

FIG. 3 shows a village 22 that pivotally supports the mirror 4 on the arm 14 of FIG.
, the parallel village 23 is pivoted to form a four-section parallel link with two upper and lower stages to form an arm 24 as a whole, and the light A from the light source section 16 is reflected by a mirror 26 provided at the extended end of the village 25, and then reflected by the mirror 26. 4 to reflect.

A light bulb 27, which consumes less power than the light source lamp 6, is provided next to the light source lamp 6 to serve as a parent and child light bulb, and only the light bulb 27 is turned on as needed to save power. FIG. 4 shows a light source 3 mounted on the upper part of an arm 30 with a joint 29 that is pivotally supported on a base 28.
1 is attached and is a light that is reflected by a mirror 4.

FIG. 5 shows a support part 33 that is horizontally rotatably supported on a base 32.
1, the lower part of a telescoping arm 34 like 5 in FIG. be.

The light source section 36 transmits the light from the light source lamp 6 to a concave mirror 37 and a convex mirror 3.
The light is projected onto the mirror 35 as indicated by the arrow A by a Cassenglen-mirror optical system consisting of 8 beams, and is irradiated as reflected light B. The irradiation position is determined by adjusting the length of the arm 34, the horizontal and vertical extensions, and the inclination of the mirror 35. FIG. 6 shows a horizontally rotatable support part 40' supported on a base 39, and a village 42 in which two telescoping arms 41 like 5 in FIG. Install the mirror 35 on the tip of the arm 41
It is pivoted on both sides.

Reference numeral 43 denotes a reflecting mirror attached to the village 42 together with the light source lamp 6.

The light from the light source lamp 6 is reflected by the reflecting mirror 43 and condensed into light A.
The reflected light B is irradiated by the mirror 35, and the irradiation position can be adjusted by vertically rotating the arm 41 against the support 40'.
Rotation in the horizontal direction relative to the base 39, expansion and contraction of the arm itself,
This is done by changing the inclination of the mirror 35. Although the above example shows a light placed on a horizontal desk surface, the base may be attached to a vertical wall, etc., or a plurality of mirrors 4 etc. may be attached to sequentially reflect the light, and the mirrors may be flat mirrors, It can be either a convex mirror, a concave mirror, or a combination thereof.

The present invention may be modified in various ways other than the above-mentioned embodiments, but all of these are included in the present invention.

Note that in the claims, the term "light" refers to a lighting device, and is not necessarily limited to a desk-top device. In the present invention, since the entire arm can be freely tilted together with the light source section and the mirror, not only can the irradiation position be changed over a wide range, but also the optical axis of the light source section can always be aligned with the center of the mirror, so the optical axis adjustment remains unchanged. These chopsticks have the advantage of being very easy to operate.
